CLOTHES-WASHER Specification of Letters Patent.

Patented Apr. 12, 1921.

Application fi1ed February 6, 1920. Serial No. 356,634.

Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Clothes-Washers, of

which the following is a specification.

This washer is designed to be used in the ordinary wash boiler and circulates in the manner of a percolator, that is to say, has a chamber with an upstanding tube from which the liquid is discharged into the mass of clothes. Heretofore difiiculty has been experienced in washers of this type in the sealing of the chamber by the clothes against the return of liquid to the chamber. One of the objects of the present invention is to obviate this difliculty. Other objects are to improve the construction involving the details hereinafter described and claimed. 7

The invention is illustrated in the accompanying drawings as follows Figure 1 shows a plan view of the washer.

Fig. 2 a section on the line 2% in Fig. 1.

1 marks the percolator tube which is preferably closed at the top and has laterally disposed openings 2 in several banks, and This is formed with a top plate 4 and sides 5. The sides are corrugated forming ribs 6, the lower ends of which form openings 7 between them. The lower ends of the projections are bent upwardly at 8 to the plane of the lower edge of the plate and an overhanging lip 9 is formed around the edge, the edge of this lip being preferably beaded at 10.

The ribs or corrugations strengthen .the sides. This is particularly true where the washer is formed of sheet metal as is the usual practice. The bottom ends of the ribs lift the edges slightlyofi the bottom of the boiler when in use so as to make a clear passage for the return flow of water and the lip 9 tends to protect the openings against sealing through the action of the clothes.

In a general way the device operates in i the same manner as devices of this character now in use, that is to say, the water returning to the chamber is converted into steam rapidly enough to force the water through the openings 2 and into the clothes and this circulation is continued so as to effect the washing of the clothes.

I prefer to form a projecting rib 11 on the tube to indicate the desired water level for the use of the device. 7 i

What I claim as new is 1. A clothes washer comprising a percolating tube; and a chamber from which the tube extends, said chamber having depressed projections along its edge forming openings permitting the ingress of water under said edge to the chamber, the edge being provided with an overhanging lip.

2. A clothes washer comprising a percolating tube; and a chamber from which the tube extends, said chamber being formed of pressed projections with intervening openings along the edge to the chamber, the side walls having an overhanging lip, the lower ends of the corrugations being upturned to the plane of the lip making a continuous lip inone plane.

In testimony whereof I have hereunto set my hand.
